When installing V6 hotend as direct drive set-up I noticed the seating is not solid. For some reason one side of BMG body has too narrow (-1.4mm) seating on the front cover (see the red lines). That allows the hotend wobble.

Printing two 0.7mm shims will make the connection solid, one the both side of the hotend neck. Adding a couple layers tape will make connection even more solid.
